Why did section 179 deduction increase my tax due amount

I am trying to see if I can use turbo tax instead of the accountant I've had. His mistakes are costing me money. I did not understand my taxes and I need to do better.)
I am entering the cost of a stove top in my rental unit. purchased and placed in service July 2021. Cost $1259.
If I elect the full section 179 my taxes due are $9,761, however my taxes due goes DOWN if I elect to spread it over 5 years. With the depreciation it shows I owe $9,662.
I thought I bigger deduction would lower my liability?
